Specification forming part of Letters Patent No. 155,038, dated September 15,1874; application filed May 9, 1874.

To all whom it may concern:

Be it known that I, JAMEs McPHAIL, of Ellis, in the county of Ellis and State of Kansas, have invented a new and useful Improvement in Iron-Ship;Builders and Boiler-Makers Gage, of which the following is a specification:

The invention will first be fully described, and then pointed out in the claim.

In the drawing, Figure l is a plan view; Fig. 2, a longitudinal section; Figs. 3 and 4, detail views in plan and longitudinal section.

A A are two guide-rods; B, a gage-head sliding on the rods, and fastened thereto by means of plate 0 and hinged clamp. E is a slotted hole-gage, ,held on the rods A A by clamp I J, having fixed hole F and slide-plate H, with ahole, G. The holes may, with it, be adjusted to any desired distance from each other.

The plate His confined in any desired position on the piece E by clamp K L. M is a scratchpiece, connected with a lip-piece, N, and may be substituted for the slotted plate E when it is desired to mark the width of angle iron whole instrument is then moved along the lapedge until hole Gr comes where F had been, and thus the places for 1 hole after hole are indicated at uniform intervals.
